Internet high speed decreased after installing Windows 8.1

Dear guys, I installed Windows 8.1 on my laptop HP Pavilion G6 2241sa.

Everything is perfect, I downloaded all the drivers, internet works fine BUT I noticed that the speed of my broadband a few minutes down from 80%. My broadband speed is 30meg to bottom/30 megs.

Download speed is reduced to 2-3megs, but upload speed remains the same...

My Network (displayed in the Device Manager) card is AR9485 of Qualcom Atheros 802.11b/g/n wifi adapter.

When I uninstall, Windows automatically detects and installs back. Internet high speed returns to normal, but after a few minutes or maybe 10 12 minutes speed drops back down, until the speed remains unchanged... I removed it 10 times, even tried to reinstall all the ralink drivers for win 8 or Win8.1, but Windows says I have the perfect driver and that it does not install anything else. I removed just in case antivirus, does not work. I checked the speed on the other computer - no problem there, but on my laptop it persists. On Windows 7, I didn't have this problem, it started after Win 8.1.   If you could please help me fix. Thank you very much. Lives

OK, this is my last post on this topic because I think I solved the problem.

I thought it was Windows 8.1 to blame, but I finally installed Windows 7. Internet was excellent, but after I installed all the latest drivers of the site Web of AMD (Amd catalyst, video driver, etc.), down speed was limited to 2 to 2.5 Mbps.

I used the system restore and Internet working again. I decided to check again, and after that I installed again the pile of last softward to Amd, I had problem once again. Prolem is therefore up to the latest version of the AMD software. Do not know exacctly what part, perhaps things like AMD stream or similar. I also believe that this issue includes my modem that does not like to communicate with my computer that has these last things AMD.

Anyway, thanks for reading. My internet gives me full speed and I am happy with that. I just create a system restore point before updating to new drivers from the site Web of AMD. It's easy to go back. A big thanks to everyone! Lives

    Ok.

    The only suggestion I can offer would be to install the latest driver ethernet directly from BCM and see if it works.

    I think you need the first driver on the list for 32 bit.

    http://www.Broadcom.com/support/?GID=9

    You will need to manually install the driver for the adapter ethernet BCM in the Device Manager, as the file contains only the driver files and no setup.exe file.

  • WiFi unstable and slow Internet high speed

    Hello world:

    Recently, I am facing a problem of unstable wifi, slow speed of the internet of my macbook pro. I hope someone could help me with my problem.


    Symptom:

    Internet mainly speed just unstable using a wifi connection. (no problem with wifi connection self and my wifi suddenly grave would not be)

    Example:

    • FaceTime with my friends and the connection would suddenly abandon or images & audio gets fuzzy.
    • Videos in online streaming and suddenly occurs buffering.
    • Download file of software update iPhone via iTunes, the speed is slow, he needed to take 2 h at the end and later on a window display "cannot download and check your internet connection".
    • Suddenly cannot open websites like site apple.com, google.com. Sometimes it will take more time to open Web sites.

    Hardware and software:

    MacBook Pro mid-2009, OS X EL Capitan 10.11.5

    ISP: Cox, 50Mbps

    Modem & router: Netgear N450

    Test:

    Turn off my wifi and connect my macbook pro with modem & router with cable, internet high speed is stable and fast. Internet speed download speed test result display is of around 60Mbps, download speed is around 8Mbps. And I tried streaming using the connection cable, there was no buffering.

    I already tried the possible Solutions:

    • Restart the Macbook pro and restart Modem & router: will not work. I mean the internet will be very well at first, but later would be unstable again.
    • Reset Wireless Modem & router and change channels: useful, but not completely solve the problem. After you change the wireless channel, I tested my internet speed and the result showing 20-40Mbps (slower than 60mbps) speed download. Sometimes, the result will be like 6-8Mbps and sometimes it will be 60Mbps. If its unstable.
    • Wireless diagnosis: result indicates connection is good.
    • Called my ISP provider: they checked and said all right.


    Other Questions & details:

    • The internet is ok for most of the time. But when all of a sudden I can't open site or I can't download and streaming & FaceTime at normal speed, his frustration.
    • I thought it might be related to my hardware since its an old macbook pro. I can't run Apple hardware test because I don't have the installation disc more and my macbook pro is very old. Is it a third party software that can perform the test hardware on mac?
    • My wifi used to be very stable and I don't have to worry. Just for these last two weeks.

  • Internet high speed only is not what it should be

    I have ThinkPad R60e, with Broadcom NetXtreme Gigabit Ethernet adapter. I guess I've always had a problem with internet high speed, but I did my best to ignore it until now. Any plan the supplier announced, I've always had a tenth only speed, download and send. I used to blame it on them, but now I changed the provider and the problem persists. So I researched what other users with the same plan, and they become quite at announced rates. So I guess there must be something wrong with the settings. Advertising plan up to 2 Mbps download and 200 kbps upload. What I get on practice is maximum of 200 kbps download and on average 20 Kbps upwards. Help, please! It is most annoying.

    I forgot to add, I use Windows XP, the problem for most with Ethernet connection since I use it the most. But wireless seems to act in a similar way.

    How will you measure your network speed.  Any chance that your bandwidth meter reports bytes/sec instead of bps?

    Sorry, I had to ask (Zoltan ducks for cover...)

  • SD card is not working properly after installing windows 10

    I have a MacBook Pro (retina, 13 inches, early 2015) with EL Capitan 10.11.5 and after I installed 10 windows using bootcamp, everything worked fine at first, but after I deleted my part of windows and then installed windows 10 the second time, the SD card is not working properly. She mounts only if the computer shuts down first, and then start. If I take the laptop directly, the SD card will not rise. The same thing happens when I switch systems using a control option key or bootcamp Center where when I switched to another system, the SD card that was mounted on the old system does not appear in the new system. I was trying to solve this problem remove the part of windows before you reinstall it again once, so I found that after I deleted the windows part, the problem is gone and it reappeared after installing windows 10 even once. I also found that after I installed windows the total volume of hard drive (128g front) became 121g.

    Hello LorinMax,

    Thanks for this info and choosing the communities Support from Apple. I know the importance of your work with your Macbook Pro SD card!

    If I understand correctly, you cannot use your SD card, unless you stop and then restart. Because this behavior started when you installed Boot Camp, I would start with the following steps:

    1. first of all, start by repairing your hard disk in disk utility to correct the unexpected problems that could be the cause of this behavior.

    Disk utility (El Capitan): a disc repair

    2. use Mode without fail to start up your Mac so that it performs certain checks, remove files from the system cache, check your startup disk and trying to fix problems if necessary directory.

    Try safe mode if your Mac does not end commissioning

    Graphics performance limited in recovery of OS X or in safe mode

    3. According to Boot Camp Installation & Setup Guide, you may need to back up your personal data and reinstalling OS X, then reinstall Windows via Boot Camp and related support files.

  • Computer OS used to start after installing windows 10

    Hello im having problem starting my system after installing windows 10. I did the install and it worked fine since the upgrade to 8.1. But then I tried to format the drive and in the menu format, he's stuck at 2%, and then I restarted the computer. Now it will hang at the hp logo and go back to the same logo. Do I have to replace my hard drive?

    What I understand, if you have completed the 10 Windows Installer and everything has happened until the end, then you are supposed to be able to do a clean install with the download of Windows 10 DVD or USB.  With a working computer, GO to THIS PAGEand scroll down to the button "download tool" selection the 64-bit version.  Once clicked, it will ask you if you want a DVD or USB for the iso.

    Once it's done and you have the DVD or the USB version, see if you can install Windows 10.  If this fails, you may need to replace the hard drive.

    After installing Windows (prior to Windows Vista) 10, scan documents with my HP Officejet 7612 became a hell of a job.

    With Webscan, I can only scan and save 1 page at a time, I can not scan several pages of the document 1 more.
